It is to be deposited;furthermore, to produce a to be understood, however, that the shank h3sling-trip which shall be composed of but a may be a separate elementand secured to few number of parts and shall be so comthe offset, or thebarBmay be reduced and 7o 2o bine-d and arranged as to present thehighest thus form the shank.

Vrange of usefulness, with a minimum danger The barsA and B are held inproper operaof breakage, and which may be operated by tive relation witheach other by means of a person of ordinary ability. the plates C, ofwhich there are two sets With these objects in view the invention shownin this instance, although a greater or 75 25 consists in the novelconstruction and combiless number may be employed, according to nationof parts of a sling-trip, as will be herethe requirements of the case.These plates inafter fully described and claimed. are arranged onopposite sides of the bars A In the accompanying drawings, forming a andB and are held in position by means of a part of this specification, andin which like bolt c, passing through the bar A, and a bolt 8o 3oletters of reference indicate corresponding 02, passing through theplates above or to parts, we have illustrated an embodiment of one sideof the bar A, as clearly' shown in our invention, although other formsof em Fig. 4t. Instead of making these plates of bodiment thereof may beemployed without two pieces of metal they may be each condeparting fromthe spirit of the same, and in structed of a single piece of metal bentto the 85 3 5 these drawingsappropriate shape. The portion of the platesFigure l is a view in side elevation with through which the bolt c2passes is bent inthe parts locked. Fig. 2 is a similar view ward to formtwo shoulders c3, which are dewith the parts unlocked. Fig. 3 is atopplan signed to prevent lifting of the bar B when view. Fig. 4 is atransverse sectional View moved by the lever E when the trip is re- 9o4o taken on the line Q3 fc, Fig. l. leased.

Referring to the drawings, A designates a The hooks or pawls D are eachprovided supporting bar or plate of metal, and prefwith a lug orextension CZ, designed to engage erably rectangularin cross-section B, atripa recess h5 in the edge of the bar thatvwill be bar arrangedparallel with the supportingthe under one in use and with a hook d2 to95 45 bar; O, a series of connected plates; D, a engage the boltc, asshown in Fig. 1. The series of chain-carrying hooks or pawls adapthookhas a rope or chain G connected with it, ed toengage with a fixed partof the bar A to constituting the sling or binder to be fas` support theload, andEa lever for operating tened around a bundle of sugar-cane orthe `the trip-bar. like, any suitable means, as a hook, being 10o 5o Thetrip-bar B works in a 'plane parallel employed to secure the end of thebinder in with the supporting-bar A, and at one end is place. The boltsc2 are engaged by ropes or Vrecesses b5, as shown in Fig. 2,

chains H, by which the apparatus may be suspended in position from asuitable overhead support.

In operation the hooks D are brought into engagement with the bolts c,with the lugs d resting in the recesses b5 of the bar B, the spring Foperating to hold these parts assembled. The apparatus is then placed onthe bottom of a cart or wagon with the slings G laid out straight, andcane or the like in sufficient quantity is loaded onto the slings, afterwhich these slings are secured in place around the bundle. The wagon orcart is then brought to an unloading station, and the bundle is liftedout of the vehicle and suspended by the chains H. lVhen the bundle thussuspended is to be released from the slings, the lever E is drawn back,thereby moving the bar B forward and releasing the hooks from engagementwith the bolts c and and causing the bundle to drop.

The mechanism for lifting the bundle from the cart or wagon may be anordinary derrick or a form of loading and unloading device, such as thatconstituting the subjectmatter of an application iiled by us in theUnited States Patent Ofice August 23, 1805, Serial No. 560,244.

Having thus fully described our invention, what we claim as new, anddesire to secureby Letters Patent, :is-

1. A sling-trip comprising a supporting bar, a trip-bar arranged inparallel relation with the supporting-bar and having recesses in one ofits edges, and sling-carrying hooks or pawls adapted to engage a fixedpart of the supporting-bar and the recesses of the trip-bar, and to bereleased by the trip-bar, substantially as described.

2. A sling-trip comprising a supportingbar, plates secured thereto, atrip-bar working between the plates, and sling-carrying hooks or pawlsadapted to engage a fixed part of the supportingbar and to be releasedby the trip-bar, substantially as described.

In testimony whereof we afiix our signatures in presence of twowitnesses.
